The brain is generally considered one organ, and yes blood delivers oxygen to the brain, so when the blood leaves the brain, it is oxygen depleted. This oxygen fuels the brain through respiration, which gives it the energy to keep you alive and constantly keep your bodily functions in line. There is a blood brain barrier though, so blood never actually enters the brain and oxygen diffuses over this barrier.
Glucose and oxygen are transported to the brain through the bloodstream. They are carried in the blood vessels and are delivered to the brain cells through a network of capillaries. The brain relies on this constant supply of glucose and oxygen to function properly.
Red blood cells don't get as far as the brain itself; they do enter the head, and provide oxygen to the cerebro-spinal fluid in which the brain bathes. What you should understand about red blood cells and the brain is that the brain is an unusually delicate organ, in which a red blood cell can actually get in the way of the normal function of the brain, by intruding into a nerve synapse. That is why the brain does not use blood directly, as other organs do.
Oxygen and nutrients are delivered to cells in the body through the circulatory system. Oxygen is carried by red blood cells in the blood, while nutrients are transported through the bloodstream to reach cells throughout the body. This delivery process is essential for cell function and overall health.
It tends to be yyour brain that is affected by a stroke when it is starved of oxygen
Oxygen
The blood transport system in the body is designed to remove waste from cells and to deliver oxygen to cells. This system is controlled by the brain and driven by the heart.
Nerve cells receive blood and oxygen through a network of small blood vessels called capillaries. These capillaries are located close to nerve cells in order to deliver nutrients and oxygen for their metabolic needs. The brain, for example, has a dense network of capillaries to ensure a constant supply of blood and oxygen to nerve cells.
red blood cells
White Blood cells help fight bacteria and red blood cells deliver oxygen to your body.
the person will die
No, the red blood cells carry oxygen.
Red blood cells
They construct and carry out the biochemical mechanisms that deliver oxygen to the body's Cells.
WIthout getting too technical, Oxygen to the cells, Carbon Dioxide on the way back
it delivers oxygen :)
Hemoglobin found in red blood cells deliver oxygen to all of our cells. The same hemoglobin also brings back carbon dioxide from the cells, which you "blow" off.
